VIBRATORY PLATFORM.

Application filed November 17, 1923. Serial No. 675,327.

To all whom it may concern:

Be it known that I, EDWARD BoWERs, a citizen of the United States, residing at Paducah, in the county of McGracken and State of Kentucky, have invented certain new and useful Improvements in Vibratory Platforms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a vibratory plat-' form for roller skating, dancing or other purposes.

One important object-is to provide a construction wherein the action of springs and pneumatic means are cooperatively used.

A further object is to provide a novel construction wherein the pneumatic means and the springs are attached in coacting relation and separately to the stationary and movable parts of the platform.

A still further object is to provide a construction in which the movable portion of the platform may be removed, in which separable retainer sections are used to hold the pneumatic elements, one section being secured to the removable part of the floor, and the other section being supported by a spring. I

Various additional objects and advan- A tages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings Figure 1 is a fragmentary view in vertical section through the platform;

Figure 2 is a sectional view taken on the line 2-2 of Figure 1;

Figure 3 is a sectional view taken on the line 33 of Figure 2;

Figure 4 is a sectional view taken on the line 4-4 of Figure 1;

Figure 5 is a detail perspective view of one of the spring-retainer-saddles, and

Figure 6 1s a detail perspective view of one ofthe retainer sections.

In car ing out the invention, the latform or oor has a suitable stationary ase as at A consisting for instance of wooden or othersills 10, in any desired number, and arranged at any appropriate distances apart. B designates the movable and removable part of the platform or floor and may consist of any suitable number of'wooden' sills 11 surmounted by a flooring as at 12, furnishing the surface for roller skating, dancing or the like.

As best shown in Figures 3 and 4, the sills 10 are provided with recesses 13. In each recess 13, an expansive metallic coil spring 14, of any appropriate tension, is disposed. The springs 14 project above the upper surfaces of sills 10 and are connected in any suitable manner to and so as to support blocks or saddles 15, of wood, metal or other suitable material.

The sills 11 and saddles 15 have concavities 16 and 16', respectively, in which retainers 17 arcuate as shown, are seated, either removably or permanently as preferred.

The terminals of the retainers 1 7 are extended outwardly as flanges as at 18.

Elements 17 position and retain pneumatic bladders or cushions 19 adapted to be inflated and deflated through the medium of suitably positioned valves 20 thereof. It will be seen that When the cushions 19 are inflated, as in the drawings, the flanges 18 are in spaced relation.

In operation, as the flooring 12 is traversed by dancers, skaters or others, the movable section B will yield with respect to the stationary section A and the movement will be cushioned by the action of both the pneumatic cushions 19 and the springs 14.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention 1. A platform of the class described having a movable floor section supported by horizontally spaced pairs of yieldable supporting means, each pair having one of its members su erimposed on the other and engaging the oor section.

2. A platform of the class described having a movable floor section, a pneumatic sup porting means therefor, retainers for said pneumatic supporting means, one of the retainers engaging the floor section, and resilient supporting means engaging the other retainer.

3-. A platform of the class described having a movable floor section, a pneumatic supporting means therefor, retainers for said pneumatic supporting means, one of the retainers engaging the floor section, and resilient supporting means en aging the other retainer consisting of a sad 1e, and a springin engagement with the saddle.

4. A platform of the class described hava stationar section, a floor section above and movab e with respect thereto, the stationary section having recesses, expansive springs disposed in said recesses and extending above the upper surface of the stationary section, saddles supported by said springs retainer sections supported by the saddles, retainer sections engaged by the floor section, said retainer sections being arranged in pairs, and pneumatic means with in pairs of the retainer sections, and the terminal edges of the retainer sections being held out of contact by said pneumatic means.

5. A platform of the class described having a movable floor section supported by horizontally spaced pairs of supporting means, each pair having one of its members superimposed on the other and engaging the floor section, the axis of each member of each pair of supporting means being at substantially a right angle to the axis of the other member, and one member of each pair of supporting means being pneumatic and the other resilient.

In testimony whereof I afiix my signature in presence of two witnesses.
